Track different domains for one website with Google Analytics

[furma]

I have two domain names pointing to the same website.
I want to know how many visitors reach each domain, separated.

Morever, Some visitors reach my domain without 'www', and I need to view the number of those either.

How do I make this separation in Google Analytics?
Please note that i have one analytics code installed within the website for more than 5 months.

Thanks for your reference.

Using Google analytics will bring to Google's attention that you are using duplicate urls for the same content, and will almost certainly guarantee the removal of most of your stuff from the index.

You need to rapidly install three 301 permanent redirects:

domain1.com > www.domain1.com
domain2.com > www.domain1.com
www.domain2.com > www.domain1.com

And remove all content from domain2.com

But that doesn't invalidate the question - if you have domain2.com correctly 301ing to domain1.com, you still may use domain2.com for a promotion and want to know how many people went through there to reach the content.
(Sorry, I don't have an answer, but wanted to point out that the question is valid. Quadrille is correct about the risks of duplicated content on multiple domains with analytics seeing it all)

Quite right; it doesn't.

But I don't have an answer for that; I suspect you may need to rely on your host's statistics for the forwarding site - but that's a guess.
